Look at source code of shell.lvl. Almost all positions and sizes of main menu elements are constant. Main menu is designed only for 800x600 resolution. The '\resolution' launch parameter and some others like '\bots' came from server executable.

We can reprogram the shell to account for widescreen resolutions. It's the ratio that's a bigger concern (4:3 vs 16:9). Some sections of the shell account for widescreen, but others do not. Might be something to add to Unofficial Patch 1.3.

just changed the button's name that now can no longer be displayed correctly and the hit box is now the yellow part. But nothing else changed. Any ideas how to resize the REAL button?This founding may helps to fix the wrong hit boxes in the high. It's not exact for the fullscreen mod.
